Ke, playing white, resigned mid-game after battling three and half hours to conclude the Human vs. Machine contest on the Chinese antient board game.

Demis Hassabis, founder of DeepMind Technology, said that it would be the last game for AlphaGo.

The 19-year-old Ke applied similar strategies from Game Two, opening the final match by creating chances of battling from the start of the game, ending with yet another action-packed performance.

Ke teared up nearing the end. He concluded the competition with a heart felt commentary repeating. "AlphaGo is too perfect."

He also expressed that bitterness over defeat will be a driving force to his future journey in exploring the mysteries of Go.

In regards to consolation, Ke first apologized, then blamed himself. Believing that he could have done much better, he said, "I faced a cold, calm and terrifying opponent, to the best of my ability, I could only predict half of AlphaGo's moves. I wish I could have done better."

When asked to share about their past five-day experience with AlphaGo, all eight Chinese Go players that took part in the Go-summit said they've learned a great deal from AlphaGo and DeepMind.
